Our great collaboration with David Doak, Jane Allison, Juliet Gerrard and Gareth Denyer is now out in Protein Science here . Peppy VR is a Unity application written by David (of Goldeneye fame), advised on by Juliet, Jane and myself and tested in real-life teaching classes by Gareth. You can get it free here for Oculus (Rift/Quest): Peppy VR.
